AIR CONTROL.

Specification of Letters Patent.

Patented May 25, 1920.

Application led July 30, 1919. Serial No. 314,196.

To all whom it may concern:

Be it known that I, HENRY M. CHEEK, a citizen of the United States, residin at Ferndale, in the county of Pulaski and tate of Arkansas, have invented a new and useful Air Control, lof which the following is a specification.

It is the object of this invention to provide novel means for controlling the amount of air admitted into the mixture of an internal combustion engine, and, in particular, the invention aims to provide novel means for regulating and mounting the valve which controls the air supply.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes inthe precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings z- Figure 1 shows in side elevation, a device constructed in accordance with the invention, parts being broken away; Fig. 2 .is an end View of the valve; Fig. 3 is a longitudinal section, wherein parts appear in elevation; and Fig. 4 is a cross section taken. approximately on the line 4--4 of Fig. 3.

The numeral 1 denotes the steering column of an automobile. .A tube 2, which preferabl is flexible, extends along the column 1 an is held upon the column by any desired number of clamps 3, of anyA selected construction. The tube 2 isheld on the column 1, additionally, b a clamp 4 comprising oppositely dispose members 5 having seats 6 adapted to receive the steering column 1 and provided with seats 7 coperating to receive the tube 2. At their ends, and between the seats 6 and 7, the members 5 of the clamp are held together upon the column 1 and on the tube 2 by securing devices 8 of any desired sort. An arm 9 projects from the seat 7 of one member 5 of the clamp 4 and is disposed approximately parallel to the steering column 1. A tubular casing 10 is secured as indicated at 25 t0 the arm 9, which arm is prolonged to form a resilient tongue or latch 19 terminating in a finger piece 20. The casing 10 is supplied at one end with a nipple 11 whereon one end of the tube 2 is mounted. The casing 10 is provided with a side port 12. A tubular valve 14 is threaded into the nipple 11 and is provided with a side port 15 coperating with the port 12 of the casing 10, the valve being closed at its outer end by a wall 16 prolonged to form a marginal flange 17 having seats 18 wherein the tongue 19 is adapted to be received.

The tube 2 may lead to a carbureter, to an intake manifold or to any other element of a like sort, for the purpose of allowing the admission of air into the mixture used in an internal combustion engine.

The tongue I19 may be sprung downwardly, by means of the finger piece 20 so that the tongue no longer is received in one of the seats 18 in the fiange 19 of the tubular valve 14. When the tongue 19 thus is Jfreed from the valve, the valve may be rotated and because the valve is threaded into the casing 10, the valve may be advanced or retracted at will, thereby to move the port 15 into and out of registration with the port 12 in the casing 10. It will be obvious that the entrance of air into .the casing 10 and into the valve 14 may be regulated accurately, at the will of an operator, by the procedure above outlined. The air is delivered by the tube 2 to the carbureter, manifold or other part of the engine. Then the ports 15 and 12 have been located properly with respect to each other, the pressure on the finger piece 2() may be relieved, the tongue 19 being engaged in one of the seats 18, thereby to hold the valve against rotation and to hold the ports 15 and 12 in any relative position to which they have been adjusted.

The device forming the subject matter of this application is so constructed and so mounted on the steering column 1, that the operator, without leaving his seat in the automobile, may at any time control the air delivered into the mixture.

It is to be observed that, in the device shown and described, the air intake is always visible and accessible, and is air tight, when' closed. The structure is positive in operation and may be worked readily from the drivers seat. Lost motion is avoided and there are no working parts widely remote from the initial point of force application.
